ROLL-FOEIdING APFABATUS.

Specification of Letters Patent.

Application filed May 17, 1915.

To all whom it may concern:

Be it known thatl, OLIVER Gmunsrr, a citizen of the United States, residing at Benicia, in the county of Solano and State of California, have invented certain. new

and useful Improvements in Roll-Forming Apparatus, of which the following is a specification.

lhe present invention relates to an apparatus for preparing sheetsof flexible material into tightly wound rolls for shipment or storage.

The invention is particularly adapted for winding sides'of leather or other stifi 1naterial into rolls, as heretofore the leather has been rolled by hand into large, loose, cumbersome bundles which occupied considerable more room than if the same had been rolled tightly;

The inventionhas for its principal objects to provide an apparatus which is adapted for tightly rolling sheets of material on a shaft; one provided with means for maintaining the material under tension while the same is being rolled; one constructed in such manner as to permit the shaft about which the same is rolled to be readily withdrawn from within the roll; and one which is simple in construction and is thoroughly efiicient for the purpose designed. I

l/Vith the above mentioned and other objects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings and pointed out in the claims hereto appended; it being understood t lat various changes in the form, proportion, size and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

To more fully comprehend the invention, reference is directed to the accompanying drawings, wherein Figure 1 is a View in plan .of an embodiment of my invention, disclosing the wind ing shaft and the platform or guide on which the leather rests as the same is being rolled. Fig. 2 is a view in side elevation. Fig. 3 is a view in detail of the winding shaft bearing. Fig. 4 is a View in end eleplate 23 Patented Dec. 7, 1915.

Serial No. eases vation. Fig. 5 is a view in detail of the winding shaft.

Referring more particularly to the several views of the drawings, wherein like characters of reference designate corresponding parts throughout the several views, 1 indicates suitable parallel spaced base members or skids which are adapted to slide and the same are connected by the transverse overhanging members 2 and 3 which are secured thereto by bolts 3. i

Suitable side frames are supported on the members 2 and the same consist of the base i, uprights 5, and top bars 6, which are connected by bolts 7, and said frames are secured in position on the members 2 by the bolts 8.

Suitable bearings 9, 10 and 11 are carried by the top bars 6 of the sideframes, and said bearings 9 and 10 are'arranged in pairs opposite each other. The bearings 9 rota tably support a stub shaft 12 which carries a gear l3, and the same intermeshes with a v pinlon lt carried by a shaft 15 rotatably squared end 21 of a main shaft 22 which is offset at its outer end and is rotatably received in the bearing 11. The bearing 11 is provided with a removable cover or top hingethas at 24c, to the base and retained in position by a yoke 25 pivotally carried by the base, and this structure permits the shaft to be removed from the bearing 11 and from the squared end of the stub shaft 12.

A clamping shaft 26 is also received at its squared end 27 in the squared end of the shaft 12, and the same extends longitudinally of the shaft 22 to a point adjacentto the offset portion thereof and between which and the shaft '22 the end of the ma terial to be rolled is clamped. A yoke 28 formed with a handle 29 is pivotally connected to the shaft 22, as at 80, and the same is adapted to engage over the free end of the shaft 26 and retain the same tightly on the leather passedbetween the shafts 22 and .26.

Secured at oneend to the members 3 are the endssof parallel spaced flexible guide and tension members 32 which are preferably upwardly inclined and terminate at a point slightly beyond the shafts 22 and 26.

1 The guide and tension members are supported midway of their length on a frame 33 and certain of the guide and tension members are slotted at their upper ends, as at 34:, to permit a tie or binder to be in- 'serted therethrough and around the tightly rolled article.

Suitable side members 34: are positioned adjacent tothe opposite side edges of the members 32 and are preferably secured at one end by angle irons 35 to the member 3, and at the end adjacent to the shafts 22 and 26 are rigidly supported by the vertical braces 36 which are braced by the connecting rod '36.

The apparatus operates in the following 1 manner :The material to be rolled is laid bers, and as the roll enlarges, the free ends to be withdrawn from within the roll.

'of' the tension members are forced downwardly. On the completion of'the formation of the roll, the material is maintained "in a rolled condition by tie members passed through the slots 3% and secured around the roll. After a roll has been thus tied the cover of the bearing 11 is raised and the shaft 22 with the shaft 26 and roll are re 'moved from the apparatus; the yoke 28 is then removed from over the end of the clamping shaft which permits the shaft 22 The clamping shaft is then withdrawn from within the roll and the shafts 22 and 26 are then assembled in the apparatus as in the drawing, at which time the apparatus is 1 adapted to be operated as before.

It willbe apparent'that the present apparatus is capable of winding material into a tight roll, is particularly adapted for use in connection with heavy and stiff material, such as sides of leather, and 1s provided with means for supporting the material before it is wound, and said means maintain the materialunder tension while winding.

Having thus described the'invention what is claimed is r 1. A roll forming apparatus, comprising a supporting frame, arotatable stub shaft, a main shaft removably associated at one end with said stub shaft and rotatably supported at its opposite end, aclamping shaft removably associated at one end with said stub shaft and between which and the main shaft the material to be rolled is. clamped,

means for drawing the free end of said clamping shaft toward said main shaft and means for supporting the material and for maintaining the same under tension as wound on said main shaft.

2. A roll forming apparatus comprising a supporting frame, a rotatable stub shaft, a main shaft removably associated at one end with said stub shaft, a bearing capable of being opened for supporting the opposite end of said shaft, means for clamping the material to the main shaft, and means for supporting the material and for maintaining the same under tension as wound on said main shaft said last mentioned means comprising flexible means secured at one end and supported intermediate of their length, the flexible ends thereof terminating adjacent to the main shaft.

3. A roll forming apparatus, comprising a supporting frame, a rotatable stub shaft, a

main shaft removably associated at one end with said stub shaft and rotatably supported at its opposite end, a clamping shaft removably associated at one end with said stub shaft and adapted to extend longitudinally of the main shaft and between which and the main shaft the material to be rolled is clamped, means carried by the main shaft for extending over the free end of the clamping shaft to draw the same toward the main shaft, and means for supporting the material and for maintaining the same under tension as wound on said main shaft.

In testimony whereof I have signed my name to this specification in the presence of I two subscribing witnesses.
